LOOM- REED.

$PECIFICATION- forming part of Letters Patent No. 536,699, dated April2,1895.

Application filed October 8, 1894.

To all whom it may concern.-

Be it known that I, WILLIAM ORR, a citizen of the United States,residing at Trenton, county of Mercer, and State of New Jersey, haveinvented certain new and useful Improvements in Loom-Reeds, fullydescribed and represented in the following specification and theaccompanying drawings, forming a part of the same.

This invention relates especially to that class of looms used forweaving wire in making wire cloth, the reeds embodying the presentinvention being of especial value as ap' plied in such looms, althoughthey may be used in other classes of looms.

In wire looms the dents must be arranged so that the warp wires arepositively guided on opposite sides, and lateral play of the wiresprevented, while at the same time it is important that allirregularities in the wires caused by knots, bends, &c., shall not catchin the dents, as would be the case if the two guiding surfaces for theopposite sides of a wirewere placed directly opposite each other and soclose together as to furnish the desired positive guide of the wire. Inweaving wide mesh fabric, moreover, and especially in large wire workwhere the wire to be beaten up is heavy, the beating up surfaces at thefront of the reed must be quite close together to secure the properbeating up of the weft. These results are secured in accordance with thepresentinvention by using dents having guiding portions equal in widthto the distance between two wires, so that the opposite sides of eachdent shall form guiding surfaces for two adjacent wires, and arrangingthe guiding portions of these dents alternately at the front and rear ofthe reed, and at a suflicient distance apart longitudinally of the warpto provide space for the easy passage of-irregularities, and byproviding beating up surfaces at the front of the reed between theguiding portions of the dents. The dents may be of various forms andsecure many of the advan tages resulting from the it vention, but itwill be found preferable to make the dents with curved guiding surfaceswhich enable the reed to swing more readily over the wires, and preventthe catch of the dents upon knots therein, and in the construction whichis Serial n 525,220. (No model.)

found preferable on account of cheapness of manufacture and durability,the guiding surfaces are oval and a very simple and efficientcombination, giving full access to the light so as to be convenientlythreaded up, may be formed by using simple oval bars of a shorterdiameter equal to the distance between adjacent wires to provide theguiding surfaces and smaller bars separate therefrom for the additionalbeating up surfaces. The additional beating up surfaces may be used onlyon one side of the reed, or if a reversible dent be desired, they may beprovided at each side so that either side may be the front or rear ofthe reed.

In the accompanying drawings forming a part of this specification thereare shown for the purpose of illustration constructions embodyingtheinvention in the preferred form, and a detailed description of thesame will now be given, and the features forming the inventionspecifically pointed out in the claims.

In the drawingsz-Figure 1 is a side view of a portion of the reed. Fig.2 is an enlarged cross section on the line 2 of Fig. 1. Fig. 3 is a viewsimilar to Fig. 2 showing a modified construction having additionalbeating up surfaces on but one side.

' Referring now especially to Figs. 1 and 2, A is the reed frame; 13,the dents, and C the wires. The dents B, as shown, are formed of simpleoval bars equal in diameter to the distance between two adjacent wires,and placed alternately at the front and rear of the reed, so that theopposite sides of each dent form guiding surfaces for two wires, and thewires while positively guided against lateral play have a freedom ofmovement between the dents to permit the passage of irregularities. Theoval bars shown are preferable to round bars as they provide moreextended guiding surfaces, thus increasing their durability, andstrengthen the bars in the direction in which the beating up pressure isexerted.

Additional beating up surfaces within the considerable space leftbetween the dents are provided in the construction shown in Figs. 1 and2 by inserting between each two dents at both sides of the reed a bar Dset sothat its front surface is in line with the front surfaces of thedents.

It is obvious that the bars D are required only at the front of thereed, but in these figures a row is shown at both front and rear makinga reed which will operate with the same effect when reversed.

It will be obvious that modifications may be made in the construction ofthe reed without departing from the invention, and I am not to belimited to the exact form of the construction shown.

What is claimed is- 1. A loom reed having dents, the guiding portions ofwhich are equal in thickness to the distance between adjacent warpstrands, said guiding portions being placed alternately at the front andrear of the reed, and said reed having beating up surfaces at the frontof the WM. ORR.
